Description
Technical field
The present invention relates to hot-rolled sheet strip steel Controlled Rolling And Controlled Cooling field, more particularly, to a kind of controllable spray of Multicarity flow
Collector.
Background technology
Controlled Rolling And Controlled Cooling quotes the production of hot rolling steel products extensively, and controlled rolling is the chemical composition in adjustment steel
On the basis of, by controlling the technological parameters such as heating-up temperature, rolling temperature, deformation system, control austenitic state and phase-change product
Structural state so that reach control steel structure property purpose.Control cooling is cold after being rolled by controlling hot-strip
But condition controls phase change conditions, Carbide Precipitation behavior and austenite structure state to realize, so as to obtain preferable tissue
And performance.
Ultrafast cool equipment is exactly the capital equipment of controlled cooling technique, and its equipment is mainly divided to two to be divided into gap nozzle cooling
Area and highly dense nozzle cooling zone two parts.Because steel plate medium temperature is high, ambient temperature is low, if inhomogeneous cooling is even, steel plate will
Deformation, easily causes steel plate side wave, the unequal product defects of performance.This requires that, along plate width direction, middle water spray is more,
Both sides will be lacked, and can just obtain good version type.If with a width of abscissa of plate, spray thrower flow is ordinate, uses curve
To represent to change along plate width direction water-carrying capacity, curve intermediate projections, both sides are low, here it is water crown curve.
Existing most cooling devices, water convexity be it is fixed, it is unadjustable.When controlling that cold steel plate material is different, thickness not
Meanwhile, the water convexity mode of this fixation will also result in the deformation of steel plate.
Patent CN101838724A provides a kind of band quenching controlled cooling collector of adjusting water convexity, discloses a kind of seam
The design of gap spray nozzle device.But this scheme real-time is poor, the large-scale stepless regulation of steel plate can not be also realized, is adjusted
The accuracy of section is also than relatively low, it is difficult to meet the processing needs of high-quality steel.
The content of the invention
It is an object of the invention to provide a kind of controllable spray thrower of Multicarity flow, steel plate cooling can be improved uniform
Property, and realize the flexible control of cooling technique.
The controllable spray thrower of Multicarity flow that the present invention is provided, including：It is horizontally installed on the resistance with holes in spray chamber body
Buddhist nun's plate, will water spray cavity be divided into above and below two chambers；The lower surface of spray thrower is set at intensive apopore, each apopore
It is respectively mounted a nozzle；
And it is vertically arranged in the long dividing plate in spray chamber body；Length direction arrangement of the long dividing plate along spray thrower,

And the connection of following table face closure, the upper chamber for cavity of spraying water at least is separated on three upper individual cavities, three along its length
Individual cavity is respectively arranged supply channel.
Whole cooling Variation Features and the control mode of supply channel and water supply valve group of the cavity according to steel plate of spraying water, by original
The single cavity shape come is divided into multiple casing shape cavitys of different shape and size, can reach the water spray of preferably regulation nozzle
The purpose of effect and cooling uniformity, obtains more preferable steel grade and template.The flow controllable precise of each cavity, makes cooling technique
It is more flexible.
Further, the aperture that aperture is 3mm~5mm is uniform-distribution with the damping sheet with holes；The aperture according to
The size of whole box-type section is arranged, and sets 5~7 rows, the pitch of holes of each row's aperture is 8mm~12mm；Aperture is with resistance with holes
On the basis of the medium line of Buddhist nun's plate, both sides symmetry arrangement.
The damping sheet with holes of such a form contributes to stationary flow, and cooling water is uniformly distributed in each chamber.
Further, described three upper individual cavities are connected by single supply channel with total watering respectively, to protect
Demonstrate,prove water temperature and the stabilization of pressure of supply water；Control valve and flowmeter are respectively mounted on each single supply channel, to realize to each
The flow in region is accurately controlled.
Further, the breviseptum is two groups, and two groups of breviseptums are on center cross-sectional of spray thrower or so pair
Claim, the upper cavity for cavity of spraying water is separated into three upper individual cavities along its length.
More than three individual cavities correspond to intermediate region and two end regions of steel plate, the flow of each upper individual cavity respectively
Controllable precise, can easily realize cooling uniformity.
Further, the breviseptum is more than 0 and no more than 45 ° for the angle between flat board, with the damping sheet with holes, with
Angle between long dividing plate is more than or equal to 30 ° and less than 90 °, and the length of the long partition part in middle upper individual cavity is accounted for entirely
The 50%~80% of long septum plate length.
Further, the apopore is in tilted layout on the lower surface thickness direction of spray thrower, apopore and spray
Angle between the lower surface of collector is 10 °~30 °.
Further, a diameter of 3mm~4mm of the nozzle, is coaxially arranged with apopore.
Nozzle inclination arranges, its water outlet and steel plate are into certain angle of inclination.Spray header uses slanting jet, make above and below
Jet area is symmetrical.
Further, the described controllable spray thrower of Multicarity flow also includes：It is separately positioned on the water spray cavity
The drainpipe of lower chambers both sides.
Drainpipe be in order to control the flow of water spray, can be from when the injection flow rate moment needed for steel plate needing to reduce very big
The cooling performance of the drainpipe outflow, preferably regulation steel plate of both sides.
Further, the lower end of the breviseptum is bent or multistage arc close to the part of spray thrower lower surface using multistage
The mode of shape, makes the lower end of breviseptum get around position where apopore.
